The purpose of this book is to help chemists, biochemists and other scientists purify the chemical reagents which they use in their work. Although commercially available laboratory chemicals are usually satisfactory as supplied for some purposes in science and technology, for many applications further purification is essential. Therefore the two main chapters of the book describe processes, taken from the literature, for purifying over 5000 organic, inorganic and organometallic commercially available chemicals. Two further chapters describe the methods and techniques currently used for purification in laboratories. In addition, for dealing with substances not separately listed, a chapter is included setting out methods for purifying specific classes of compounds. Finally, there is a new chapter dealing with biological substances which indicates current methods of purification in this area. This expanded and revised third edition includes several hundred individual compounds not previously covered, and more information is given for most entries, including melting and boiling points, molecular weights, refractive indexes, densities and Chemical Abstracts registry numbers, as well as likely contaminants and storage conditions in some cases. In addition, safety information and hazardous substances are indicated as appropriate. Recent developments in techniques of purification have also been added, including new chromatographic methods and materials.

Purification of Laboratory Chemicals is vital for minimizing potentially dangerous reactions, as well as maximizing the integrity of chemicals used to process a product that must adhere to rigorous scientific standards.From the Publisher:
Chapter 1 has been reorganized and updated, and most of it is in smaller print in order not to increase the size of the book. Chapters 2 and 5 have been similarly altered and combined into one chapter, Chapter 2, again in order to save pages. 800 and 350 entries have been added to Chapter 3 (25% increase) and Chapter 4 (44% increase) respectively, and 400 entries (310% increase) were added to Chapter 5 (Chapter 6 in the third edition) making a total of 5700 entries, all resulting in an increase from 319 to 529 pages, i.e. ca 35%. This considerably expanded and revised fourth edition includes much new material dealing with modern reagents for natural products chemistry, protein biochemistry and molecular biology. It also includes many individual compounds not previously covered, and more information is given for most entries, including melting and boiling points, molecular weights, refractive indexes, densities and CAS registry numbers, as well as likely contaminants and storage conditions in appropriate cases.
